Configuring Mtu And Mss; Configuring Dhcp Hostname - Sense SG-2440pfSense Quick Start Manual

Configuring MTU and MSS

Figure 10
MTU or Maximum Transmission Unit determines the largest protocol data unit that can be passed onwards.
A 1500-byte packet is the largest packet size allowed by Ethernet at the network layer. Leaving this field
blank allows the system to default to 1500-byte packets. PPPoE packets are slightly smaller at 1492-bytes.
We recommend leaving this blank for a basic configuration. MSS and MTU must be set to the same packet
size if you configure them.

Configuring DHCP Hostname

Figure 11
Some ISPs specifically require DHCP Hostname entry. You may leave this blank, otherwise.
